The latch element 25'is 55 hook 30 as shown in Fig. 2 for mounting the latch element in this position. The latch element 25 is limited in its pivoting to the right or the left by a lug portion 3| which projects from the member I0. 'I'his lug portion acts as a stop against which the edge 2S of the latch member engages.

In Fig. 1 the conventional hook fastener is shown. It comprises iiexible adjacent strips 32 and 33 on the adjacent edges of which there are mounted engageable hooks 34. These hooks are engaged between the anges I5 and I6 of the trapezoidal members which are adapted to relatively bend and interengage or dis-engage the hooks from each other, depending merely on the direction in which the slide is moved. The projections I2 act as a wedge yfor engaging or disengaging the hooks 34. It should be noted that the spacer portion I4 merely forms a stop against which the projections I2 engage (see Fig. 5) to correctly hold the guide members in their closed operative positions. 'I'he trapezoidal member I0 is formed with an opening 36 through which the' finger 29 passes.

The operation of the device is-as follows: When they handle 21 is swung to the position shown in Fig. 1 it is possible to force the handle to one side or the other to pivot the latch element 25 and disengage it. from the hooki30. The trapezoidal members I0 and II may be pivoted .apart a short distance as illustrated in Fig. 12.v

When thus pivoted, the trapezoidal guide members are open and it is possible to remove the hook fastener slide from the hooks 34.`

In Fig. 13 a modified form of the invention has been disclosed which distinguishes from the previous form merely in the .fact that the open element I3 is integralwith the trapezoidal guide element II. The parts may thus be\`cast as one unit The necessity Vfor the opening Il and rivet portion I 8 is thus eliminated. In other respects this form of the invention is identical to the' previous form and similar parts may be recognized by the identical reference numerals.

In Fig. 14 another modified form has been disclosed which distinguishes from the prior form merely in the construction of the bearing loops 20. These bearing loops are completely annular and formed by casting or similar operation. They distinguish from the loops 20 in that the latter are bent into form and thus have free ends.

While I have illustrated and described the preferred embodimentssof my invention, itis to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as dei-ined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is: l

`1. In a hook fastener slide, a pairA of trapezoidal guide members having opposed wedge shaped projections at their larger, ends, and a post element riveted on to one of said members and pivotally associated with the other of said members andhaving a spacer portion disposed lbetween said projections for limiting closing of said members.

2. In a hook fastener slide, a pair of trapezoidal guide members having opposed wedge shaped projections at their larger ends, and a post element riveted on to one of said members and pivotally associated with the other of said members and having a spacer portion disposed between said projections for limiting closing of said members, said wedge shaped projections being formed with slots through one of which said post element is riveted, and through the other of which the post element passes. 3. In a hook fastener slide, a pair of trapezoidal guide members having opposed wedge shaped projections at their larger ends, and a post element riveted on to one of said members and pivotally associated with the other of said members and having a spacer portion disposed between said projections for limiting closing of said members, said wedge shaped` projections being formed with slots through one of which said post elementris riveted, and through the other of which the post element passes, the material to the sides f the slots of the pivotally mounted trapezoidal guide member being formed with curled portions forming bearings for receiving a pintle engaging through said post element for pivotally connecting these parts.

4. In a hook fastener` slide, a pair of trapei zoidal guide members having opposed Wedge shaped projections at their larger ends, and a post element riveted on to one of said members -and pivotally associated with the other of said members and having a spacer portion disposed between said projections for limiting closing of said members, one of said guide members being formed with a pivot portion integral therewith for receiving a latch element adapted to latch the guide members in operative positions.

5. In a hook fastener slide, a pair of trapezoidal guide 'members having opposed wedge shaped projections at their larger ends, and a post element riveted on to one of said members and pivotally associated with the other of said members and having a spacer portion disposedA between said projections for limiting closing of said members, one of said guide members being formed with a pivot portion integral therewith for. receiving a latch element adapted to latch the guide members in operative positions, with the wedge shaped projections engaging said spacer portion.
